Abstract
Three specimens of a rare labrid, Suezichthys notatus (Kamohara, 1958) were recently collected from local markets, which were captured from deep-water off northern and southwestern Taiwan, and represent a new record for Taiwan. Suezichthys notatus can be distinguished from its congeners by a combination of characters: scale rows above lateral line 2½; low scaly sheath present at base of dorsal and anal fins; dorsal-fin element IX, 11; anal-fin elements III, 10; lateral line scales 25‒26, each with simple, unbranched laterosensory canal tube; cheek scale rows behind and below eye 2 and 2‒3 respectively; a group of prominent dark blotches extending from the interorbital region dorsoposteriorly; body depth at dorsal-fin origin 3.7‒3.9 in standard length; short pelvic fin without filamentous extension, 2.2‒2.5 in head length. Suezichthys resembles the labrid genus Pseudolabrus, comparison of Taiwanese species of Suezichthys with those of Pseudolabrus are given.
Highlights
The labrid fish genus Suezichthys was originally proposed by Smith (1957) as Suezia, and subsequently replaced by Suezichthys
Suezichthys notatus (Kamohara, 1958) was briefly described from a single specimen collected from Okinoshima, Kochi Prefecture, Japan
Russell (1985) noted the holotype of S. notatus had been re-examined by Takeshi Yamakawa, who reported a 16 total gill rakers, instead of 4 + 1 + 9 = 14 as given by Kamohara (1958)
Summary
The labrid fish genus Suezichthys was originally proposed by Smith (1957) as Suezia (a name preoccupied in Crustacea), and subsequently replaced by Suezichthys (see Smith 1958).
